Case Studies

A manufacturer of oil field gas analyzers opened a project to reduce the on floor assembly time of their main product. The largest issue was the time it was taking to attach a complex-shaped silicone heater to a cylindrical shaped aluminum vessel. The company’s exacting quality requirements made it necessary to carefully make sure there was no entrapped air between the heater and vessel and that all corners were carefully attached. This was important to ensure temperature uniformity of the vessel as well as prevent premature heater failure.…

As part of a new equipment redesign, a manufacturer of food service equipment discovered that an obstruction in the new piece of equipment prevented direct insertion of the temperature sensor probe as in previous generations of equipment. The obstruction could not be penetrated to allow sensor installation. The manufacturer contacted Durex to determine if a solution could be suggested that might prevent equipment redesign.…

A large mining project executed in the Tar Sands of Canada required several hundred immersion heaters to be specified for installation into rock crushing and mining equipment in order to keep gear boxes and lubrication systems operating at peak performance in temperatures down to -40°F.…

A large manufacturer of aerospace battery packs had a new requirement for a space saving lithium battery pack. The requirements presented a challenge to the normal silicone heater power lead configuration due to a maximum thickness specification. The space envelope would only allow for .080" thick for the flexible heater at its maximum thickness including the power lead thickness.…

A manufacturer of specialty chemicals needed to develop a batch chemical manufacturing process that required precise, multi-tank as well as multi-zone heating and control parameters in order to achieve desired product characteristics and high yields. If successful, the manufacturer was looking to expand production.…

A manufacturer of car wash systems had a need to provide a heater and control panel in a wash system that was already installed at the customer site. Space was very constrained. The heater had to be installed between 2 pump stations and the control panel needed to be located nearby – but where?…
